INTRODUCTION
This version of the CCD42 family of CCD sensors has full-frame
architecture. Back illumination technology, in combination with
an extremely low noise amplifier, makes the device well suited
to the most demanding applications, such as astronomy.
The output amplifier is designed to give excellent noise levels at
low pixel rates and can match the noise performance of most
conventional scientific CCDs at pixel rates as high as 1 MHz.
The low output impedance and optional FET buffer simplify the
interface with external electronics.
The readout register has a gate controlled dump-drain to allow
fast dumping of unwanted data. The register is designed to
accommodate four image pixels of charge and a summing well
is provided capable of holding six image pixels. The output
amplifier has a feature to enable the responsivity to be reduced,
allowing the reading of such large charge packets.
The device is supplied in a package designed to facilitate the
construction of large close-butted mosaics and is designed to
be used cryogenically. The design of the package will ensure
that the device flatness is maintained at the working
temperature.
The sensor is shipped in a protective container, but no
permanent window is fitted.
